Application 01
Oil sands and shale produced water
AQUA-SEP® vacuum membrane distillation recovers water from high-brine produced water so it can be reused, for example as steam for bitumen production, instead of being disposed of.

Oil, Gas & Energy
plants and separation, end to end.
We fabricate the equipment and the plants that oil, gas, and energy operators run on, and we bring our own membrane IP for the streams that defeat conventional separation. Pressure vessels, separators, slug catchers, gas-processing skids, and full packaged units, built in our shops, ASME code-stamped at Kerteh where required. Where the fluid is hard, we add patented membrane systems for produced water, frac flowback, and BTEX recovery, across upstream production, midstream processing, LNG and gas processing, and refineries.
What you get
Outcomes our customers see.
Specific to oil, gas & energy.

- Feed salinity handled
- 25%+ salt
- AQUA-SEP® processes high-TDS feeds above 25% salt, beyond the practical limit of reverse osmosis.
- Footprint, 100 m³/day plant
- 2 skids
- 5.5 × 5.5 × 5 m and 6.5 × 2.5 × 5 m, per the AQUA-SEP® brochure.
Lab test results
Frackwater lab data, three feeds.
Real samples, real numbers. Recoveries and permeate quality from Petro Sep's lab tests of AQUA-SEP® on frackwater samples from three named sources. Source: Petro Sep General Presentation, 2024.
| Feed source | Feed salt (TDS) | Permeate salt | Water recovered |
|---|---|---|---|
| Marcellus | 2.4% | 0.001% (10 ppm) | 90% |
| Texas | 8.1% | 23 ppm | 88% |
| Western Canada | 13.8% | 7 ppm | 80% |
Each row is a real frackwater sample tested in the lab with AQUA-SEP® membranes. To see how your own feed behaves, ship us a sealed sample from your operation and we will return characterized recovery and permeate-quality data inside two to six weeks.

What we deliver.
The specific scopes and separation problems we solve for oil, gas & energy operators.
Application 02
Frac flowback treatment
On-site treatment of mixed brines and hydrocarbons for reuse in the next stage or compliant discharge.
Application 03
BTEX and VOC capture
Recovery of valuable volatile organics from aqueous streams, in compliance with state and provincial limits.
Fabrication scope
What we build for this sector.
Most oil and gas projects start with a fabrication scope: separators, columns, slug catchers, gas-processing skids, or a packaged unit. Our Kerteh shop handles ASME U, U2 & R code-stamped pressure equipment, sour-service materials, and full skid packaging. PSE Malaysia recently delivered two Acid Gas Oxidizer (AGO) STACK units, each 40 metres long.

Membrane technologies
The right process for the fluid.
Oil and gas streams almost never look like a single problem. We pair technologies, often combining VMD on the water side with pervaporation on the hydrocarbon side, to deliver a turnkey system rather than a single unit.
VMD
Vacuum Membrane Distillation
High-recovery treatment for high-salinity and complex feeds where reverse osmosis cannot go.
Learn more
PV
Pervaporation
Selective separation of liquid mixtures, including the azeotropes that distillation cannot break.
Learn more
VP
Vapor Permeation
Vapor-phase separation for solvent dehydration and VOC recovery in chemical and pharmaceutical operations.
Learn more
ZLD
Zero Liquid Discharge
Closed-loop systems that recover water and isolate solids for industrial wastewater.
